   Measurements taken with membrane conditioned to 23°C, 50% RH for 24h.

   Conductivity measurement taken at 23 °C, 100% RH.

   A base titration procedure by using the caustic soda measures the equivalents of sulfonic acid in the membrane, thus calculating the acid capacity or equivalent weight of the membrane.

   Water content of membrane conditioned to 23 °C and 50% RH (dry weight basis).

   Water uptake of dry membrane conditioned in water at 100 °C for 1 hour (dry weight basis).
